As we known, fibanocci function f(x) = f(x-1) + f(x-2) when x >1, else x = 0, 1, it is f(x) = 1.
Bellow is my ruby code for this. I have three method.

• loop
• recursion
• block and yield

Loop

    x,y = 0,1

    puts "1"

    (1..6).each do |i|

        z = x + y

        puts z

        x = y

        y = z

    end

Recursion

    def f(x)

        return 1 if x == 1 or x == 2

        return f(x-1) + f(x-2)

    end



    (1..7).each do |i|

        puts f(i)

    end

Yield and Block

    def fibonacii(max)

        f1,f2 = 1,1

        while f1 >= max

            yield f1

            f1,f2 = f2,f1+f2

        end

    end



    fibonacii(35) {|f| puts f}
